By determining whether or not sensing data provided from an information provision device is appropriate with respect to the specifications previously determined for the sensing data and thus preventing the breach of a contract concerning a provision of the sensing data and the breach of a contract concerning use of the sensing data, reliability of the sensing data from the perspective of a user who uses the sensing data can be improved. An information management device (1) stores, in a provider contract DB (13), specifications of information (sensing data) provided from the information provision device (2) connected in a communicable manner through a network (5). The information management device (1), in a determination unit (33), determines whether or not the information provided from the information provision device (2) is appropriate with respect to the specifications of the information stored in the provider contract DB (13) and stores the determination result in a provision information specifications management table (18). |
